5.2.3 Axis monitor devices 2

(1) Current value (D800+20n, D801+20n) .................. Monitor device
(a) This register stores the address in the work coordinate system (G54 to G59)
specified with the Motion program.
This value is stored on the assumption that 0.0001mm is equal to 1.
(1mm=10000)
Example that the setting using the peripheral device is G54=1000 is shown
below.
Machine value
Current value
At the 10000000 position of the machine value, the current value is "0".
(b) The current value is shift depending on the work coordinate system
selection (G54 to G59) and G92 (coordinate system setting).
When "G90 G00 X0. ; " (G54 selected) and "G92 X500." are executed in
the above state, the current value is as follows.
Machine value
Current value
Execute "G92 X500."
The 0 position of the current value is re-set to 500. , which results in the
current value of 5000000.
